That is, the packing member 20 is sandwiched between the lid base portion 5 and the upper end opening edge of the mouth portion main body 2a of the container main body 2 via the flange portion 4b. At that time, the packing member 20 is pressed against the flange 4b, so that the crushing protrusion 20b is crushed by the upper end opening edge of the mouth 2b.

Thereafter, when the movable lid portion 6 is further raised with respect to the container body 2, the movable lid portion 6 and the dropper tube 8 rise together through the engaging portion 29. As a result, the dropper tube 8 is extracted from the container body 2 and the dropper cap 3 is detached from the container body 2. At this time, since the pressing force to the crushing protrusion 20b of the packing member 20 is released, the crushing protrusion 20b is deformed and protrudes. And the content in the dropper tube 8 is poured out from the lower end opening of the dropper tube 8 by pressing the membrane tube part 11 b of the lid 11 with the dropper cap 3 detached from the container body 2.

  • the valve element 27 closes the upper opening of the dropper tube 8 in the initial state. Therefore, for example, even when the lid 11 is unintentionally operated in the initial state, it is possible to prevent the contents in the container main body 2 from flowing into the dropper tube 8 by mistake. For this reason, it is possible to ensure a constant amount of the content dispensed from the dropper tube 8 with high accuracy. Furthermore, for example, even if the contents of the container body 2 flow into the dropper tube 8 due to the dropper container 1 falling in the initial state, the contents can be blocked by the valve element 27. For this reason, it is also possible to regulate the flow of the contents into the space 16.

  • the packing member 41 is displaced between the lid base portion 5 and the upper end opening edge of the mouth portion 2b of the vessel body 2 to displace inside the vessel body 2. This is suppressed by the locking protrusion 42 being locked to the outer peripheral surface of the upper end opening of the container body 2 (the outer peripheral surface of the flange 4b of the guide tube 4).
  • the sealability by the packing member 41 can be secured satisfactorily, and deformation and deterioration of the packing member 41 due to long-term use can be suppressed.
